Buying expensive gas for your BMW or any other vehicle might be costly. You may be able to save money by using ordinary fuel depending on the model of your BMW, but there will be a cost. We think that saving money right away isn’t worth endangering your car.
Thanks to more electronic components, most new BMWs can run on ordinary gasoline, but this might put stress on several elements, including the electronic knock sensors in your engine. These electrical parts provide the engine the ability to recognize the sort of fuel it’s using and alter performance accordingly, protecting your engine.
Regular fuel has the additional drawback of altering the performance of your engine, which results in a reduction in power and slower acceleration. But this isn’t a significant loss. Most vehicles that are advised to use premium fuel but switch to normal gas will lose around 10 HP. This is something to keep in mind, especially if you bought your BMW for its power, even if it probably won’t be a major concern if you only use it to get around town.
There are some exceptions to this rule, just like with anything. Certain BMWs do need premium fuel.
These are the most typical causes for a BMW to need premium, but this is by no means a complete list. In the event that your BMW fits one of the following descriptions, avoid using normal gasoline in it:
- Your vehicle predates the 1996 model year.
- It’s a model M.
- It has a turbo engine or one with high compression.
- Your model of vehicle must utilize premium gasoline, per BMW (they recommend that all of their cars use premium, but only require it on select models)
A complete list of BMWs (model years 2012–2019) that demand premium can be found here, while a list of BMWs that recommend premium but can operate on regular can be found here. Remember, though, that continuing to run as usual can have negative effects. Above all, before converting from premium to normal unleaded, always consult your owner’s manual.

Can ordinary gas be used in a BMW 328I?
The quick response is: NO! We do not advise using subpar fuel in BMWs. Triangle Imports does not subscribe to such ideology, despite the fact that some models may suggest this as a workable choice while reading the owner’s manual.
Can 89 octane fuel be used in a BMW 328I?
323i,328i/xDrive: 87; 335i/xDrive: 89 are the minimum AKI ratings. When starting the engine at high outside temperatures, the engine may make knocking noises if you use gasoline with this minimal AKI Rating. The engine life is unaffected by this. Use only gasoline that meets the required minimum grade.
What kind of fuel is recommended for BMW?
What type of fuel does a BMW require then? As we previously stated, premium gas is ideal for a BMW. Because premium gasoline has a higher octane rating and is better suited to high compression engines, it is the optimum fuel for BMW vehicles. Regular gas only has an octane rating of 87, but premium gas might have a rating of 92.
What happens if I fill up my BMW with 87 gasoline?
While my Toyota is in the repair for the next several days, I’m borrowing my brother’s BMW, and I unintentionally put ordinary gas in the vehicle. I assumed BMWs used some kind of premium fuel. What occurs if ordinary gas is accidently poured into a BMW?
In less than two minutes, find out if your auto insurance is being overcharged.
The quick response is nothing. You won’t run the risk of damaging your brother’s automobile because the majority of BMWs can run on ordinary gas.
When you fill up a BMW with standard gas instead of premium, the car will detect this and may operate with a little less power and timing, but all of its components will function as intended. BMWs are equipped with sensors that can identify the type of fuel being used and will adjust the engine accordingly.
If you still feel guilty about filling up your brother’s BMW with ordinary gas, make up for it by showing him the Jerry app and assisting him in saving hundreds of dollars on his auto insurance.
After you download Jerry, all you have to do is respond to a few questions that will take you around 45 seconds to do, and you’ll get car insurance rates for coverage that is identical to your current plan right away. Customers of Jerry save $887 year on average.
What is the best gas station for a BMW?
The addition of ethanol to petrol has become customary as a result of our continually growing dependence on oil. The main purposes of ethanol are to assist oxygenate the fuel and serve as a consumable, re-usable filler. The fuel known as E10 must contain 8–10% denatured ethanol to meet Top Tier regulations. Non-Top Tier fuels can range, and when too much ethanol is present, water is absorbed and over time accumulates at the bottom of the fuel tank beneath the lighter floating gasoline, which can cause rust and drivability problems. Although it is true that for the past ten years, the majority of BMW gasoline tanks have been made primarily of plastic, therefore rust is typically not an issue. By preventing deposits on fuel injectors, combustion chambers, and intake valves in particular, high-quality additive packages for Top Tier fuels assist in the maintenance of your engine’s internals (non-direct injection).
Does the BMW 3 Series need premium fuel?
No matter what model you have, BMW advises only using premium unleaded fuel. That’s not to say that your BMW won’t run on inferior fuel, but premium unleaded fuel will keep its quality over time, allowing you to constantly drive at peak performance.
What happens if I don’t fill up my BMW with premium fuel?
BMW, for instance, advises using premium fuel in all of the vehicles it sells in the United States, though they can also run on ordinary. According to Thomas Plucinsky, a BMW representative, using lower-octane fuel normally doesn’t hurt the engine.
Is 93 octane suitable for a BMW?
It seems terrible to even consider using normal unleaded in this $129,595 intercontinental ballistic missile. Although that appeared unlikely in such low temps, using the cheap stuff would have been totally out of character with what an owner would do. BMW expressly forewarns about engine harm from doing so (at least until this M5 reaches its fourth owner sometime in 2036). In order to comply with BMW’s requirement for 91-octane fuel, with 93 being suggested, we switched between the popular types of premium petrol based on the state you’re in. Are Californians leaving money on the table with their diluted premium? We were curious.
The dyno findings were unexpected. No, not because 91 and 93 octane have 13 fewer horsepower. No, the delta was within the expected range. Just how much power and torque we measured left our jaws hanging. The uber 5-series is incredibly undervalued on either fuel. While BMW claims 617 horsepower at the crank, the dyno shows that it produces that amount at the wheels on 93-octane premium fuel (after driveline losses). Furthermore, both fuels provided a lot more torque than the 553 lb-ft of claimed torque from BMW.
The acceleration times of the M5 were all reduced by a single tenth of a second thanks to the higher-octane fuel. This propels the five-seat, 4246-pound four-door into the realm of supercars with a time-bending 2.7-second slingshot to 60 mph and 10.8 seconds through the quarter-mile. Although the BMW claimed to have the highest fuel efficiency margin in the test, the lower octane was preferred due to a 0.7 mpg differential. The M5 Competition is evidence that the octane rating does matter, but with these two premium fuels, using 91 octane won’t leave you significantly worse off.
Why does a BMW need premium fuel?
91+ octane fuel is the fuel created exclusively for use in BMW high-compression engines. Because it optimizes engine function and reduces fuel waste, you can travel farther on a single tank of gas, increasing your miles per gallon.
What occurs if 89 fuel is used in an 87 vehicle?
Do not become alarmed if the manufacturer of your automobile or truck suggests premium fuel for your vehicle but you instead use normal. Even though premium is advised, you are not required to use it; the engine can run just as well on standard gas.
You can run into issues if you use standard fuel when your manufacturer calls for premium. How well your car or truck will handle normal petrol depends on the sophistication of your fuel system as well as other elements like how your engine is tuned, what the timing is, and how hot it runs. Most of the time, the car will run just fine, although you might notice less power and reduced gas mileage. Because the fuel isn’t burning properly in more acute cases, you might hear engine banging or valve chatter. You should take it to your mechanic because these things might harm your engine.
Can 87 and 91 gas be combined?
Yes, drivers are allowed to mix the two fuel kinds. According to The Drive, the mixture of gas types will produce an octane level somewhere in the center, which the vehicle “will survive.”
Do vehicles actually require premium fuel?
Some high performance and luxury cars need premium gas, which is defined as gas with an octane level of 91 or higher. High octane gasoline has a harder time igniting, which helps high performance engines avoid pre-ignition and knocking. If you frequently fill up with ordinary when your vehicle needs premium fuel, the engine could become damaged.
What happens if premium and normal gas are combined?
Can I combine unleaded and premium gas? Yes, drivers are allowed to mix the two fuel kinds. According to The Drive, the mixture of gas types will produce an octane level somewhere in the center, which the vehicle “will survive.”
Is 89 premium gasoline?
Each state has its own definition of what constitutes premium gasoline. So, if you’re driving across the country or between states, pay attention. For a fuel to be deemed premium, one state would demand an octane rating of 92, while another might simply require 90. There are typically three octane ratings available at gas stations in the United States: ordinary (often 87 octane), mid-grade (typically 89 octane), and premium (usually 91 or 93 gas). To find out which one you are getting, look at the sticker on the pump.
Can I substitute 89 octane for 91?
When a vehicle manufacturer specifies premium fuel, it’s because the fuel system of that specific vehicle is built to function best with higher octane fuel. In an engine that needs premium fuel, using normal petrol could violate your warranty. That is most likely to occur if repeated use results in severe engine knocking or pinging (premature fuel ignition, also known as detonation), which harms the pistons or other engine components. Other issues, such as worsened engine performance and poorer fuel economy, may result from using the incorrect gasoline.
As an illustration, the following is what GM states about the matter in the owner’s guide for a car that needs premium:
“Use 91 octane or higher premium unleaded fuel that has been posted on the label. If the octane level is below 91, you risk damaging the engine and voiding the warranty on your car. When using gasoline with an octane rating of 91 or above, the engine requires maintenance if loud banging is observed.”
Keep in mind that this only applies to engines that demand premium gas. Although some manufacturers advise using premium gas, you can also use standard or mid-grade gas. Usually, they mention that using gas with a lower octane rating could affect performance and fuel efficiency. They advise using premium when that starts to become noticeable, or if engine knock starts to happen.
